How Do We Communicate With Spacecraft? We Asked a NASA Expert

How do we communicate with spacecraft? For decades, satellites have beamed data back to Earth by way of radio waves, with a network of ground-based antennas collecting the incoming information. Now, we're exploring laser communications, technology that will allow us to receive more data from farther than ever before -- faster, too.
